Pipeline Safety: Class Location Requirements

Notice of inquiry, extension of comment period.

On August 1, 2013, PHMSA published a notice of inquiry in the Federal Register on "Class Location Requirements," seeking comments on whether integrity management program (IMP) requirements, or elements of IMP, should be expanded beyond high consequence areas (HCA) and, with respect to gas transmission pipeline facilities, whether applying IMP requirements to additional areas would mitigate the need for class location requirements. PHMSA has received two requests to extend the comment period to allow stakeholders more time to evaluate the notice of inquiry. PHMSA concurs with this request and is extending the comment period from September 30, 2013, to November 1, 2013.
